--- Comment #1 from Eli Friedman <efrie...@codeaurora.org> ---
Tried compiling your testcase with -fsanitize=undefined; ubsan says:
<stdin>:109:22: runtime error: signed integer overflow: 2147483647 -
-2147483648 cannot be represented in type 'int'
We make no guarantees about the behavior of code with undefined behavior. See
also http://blog.llvm.org/2011/05/what-every-c-programmer-should-know.html .
(For signed integer overflow in particular, you can use the flag -fwrapv to
make it have defined behavior.)
